SPRING BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 275,497, dated April 10, 1883.

Application filed February 14, 1883. (No model.) Patented in` Germany April 23, 1880, No. 12,402 in Belgium December 15, 1881,

No. 5,634, and in Austria-Hungary December 31, 1881, No. 35,220 and No. 43,800.

To all whom it may concern.-

Be it-known that I, PETER HEINRICH KEsE f BERG, of the city of Hamburg, in the Empire of Germany, have invented certain new and useful Improvements in Spring Bed-Bottoms, (for which Letters Patent have been granted tome in Germany, No. 12,402, dated April 23, 1880; Austria-Hungary, Nos.35,220 and 48,309, dated December 31, 1881, and Belgium, No. 5,634, dated Decemberl, 1881,) ot which the following is a specilication.

This invention has reference to improvements in spring bed-bottoms; and the invention consists of a bed-bottom composed of longitudinal and transverse slats, the latter carrying spiral springs, which are provided at their upper ends with wooden or metallic blocks that are connected by longitudinal and transverse metallic bands or straps. The head-section of the bedbottom is made vertically adjustable by placing the springs on inclined strips, which are adjusted higher or lower by a suitable adscribed hereinafter. x

In the accompanying drawings, Figure 1 represents a side elevation, and Fig. 2 a plan, of a bed-bottom for single or double beds. Fig. 3 is a plan of a bed-bottom for narrower bedssuch as ship and car berths. Figs. 4 and 5 are end elevations of the adjusting mechanism of the head-section. Fig. 6 is a side elevation anism. Figs. 7 and 8 are respectively a vertical central section and a bottom view ot' one of the spiral springs and its connection with the top block. Y

Similar letters of reference indicate corresponding parts.

My improved bed-bottom is constructed of longitudinal base-slats a. a, to which a number of transverse slats,b b, are applied. The spiral v supporting-springs d of the bed-bottom are seated-at their lower ends in circular grooves of the transverse slats b b, and secured at their upper ends to corresponding grooves of wooden or sheet-metal heads or blocks e e, of round or polygonal shape, which blocks are attached to the springs by means ot' pivoted catches (shown in Figs. 7 and 8,) or by any other equivaient fastening device. The blocks e are connected by longitudinal and transverse sheetmetal bands or strapsff, which are retained in bottom grooves at the under side ofthe blocks e e, and secured thereto by rivets, staples, or

otherwise. The sheet-metal straps or bands f f impart the required degree of stiliness and rigidity to the bedbottom andtransfer the pressure from one top block to the adjoining blocks,- so as tocall a number of springs into action when pressure is exerted thereon.

The head-section a' of the bed-bottom is so arranged that the longitudinal bands f run continuously through from the main part of the bed-bottom to the blocks ve of the head-section, thetransverse base-slats of which latter are, however, not supported on the longitudinal base-slats a a, but-on inclined strips a?, which are guided by their grooved front ends on short rods a3, attached to thebase-slats a c. The inclined head-strips a2 are either notched at the under side and supported at a greater or less angle of inclination to the base-slats a a on a transverse strip, h, which is secured to slideblocks h', that may be moved forward or backward on the rods a3, as required, for the adjustment of the head-section, as shown clearly in Fig. 1 or the head-section a may be supported by one or two toothed rods, t', applied to a transverse piece, t', which latter is pivoted to the inclined adjustable strips a2 of the head-section a', as shown in Figs. 4, 5, and 6, in which case the toothed rod or rods t' are locked by means of spring-catches t2, that may be withdrawn by means of strings t3 or otherwise from the teeth of the rod or rods, so as to facilitate the raising or lowering of the headsection a. The inclined stri ps a2 are guided in the latter construction in the same manner on the guide-rods al of the base-slats a a as in the construction shown in Fig. 2.

When the bed-bottom is used for narrow beds or berths the numberlof transverse baseslats maybe reduced-in fact, only two at the head and foot end are required, as shown in Fig. 3. The longitudinal straps or bandsfj', however, are continued through the adjustable head-section a', said bands forming the connectinglinks ot" the main part and head-section. In place of the metal bands or straps, cane-straps may be used.

ICO

The advantages of my improved construction are that the head-section may be adj usted to different inclinations, that the entire bedbottom may be quickly assembled and put to gether, and that any one ofthe spiral springs may be readily exchanged in case of breakage or wear.

Having thus described my invention, I claim ns new and desire to secure by Letterslatentl. As an improvement in bed-bottoms, thc combination ofthe longitudinal slats c a, transverse slats b b, spiral supporting-springs di d,

top blocks, c e, secured to the upper ends of the springs, and longitudinal and transverse straps or baudsff, secured to the under side of the blocks, substantially as set forth.

2. The combination of :i bed'bottom constructed ot longitudinal slats a u, transverse slats b b, spiral springs dd, blocks ce, and longitudinal and transverse bands or straps ff', with a head-section, a', connected to the main portion by the longitudinal strapsf, and being Supported on inclined and guided basestrips a2, provided with mechanism for adjusting the head-section higher or lower, substantially as specified.

3. As an improvement in spring-bed bottoms, the combination, with the main portion ofthe bed-bottom, of an inclined headsection, the spring-supported head-blocks of which are connected to the head-blocks ot' the main portion by longitudinal bands or straps, said headsection having inclined basestrips guided on the base slats of the bed bottom, and mechanism for adjusting the base-strips higher or lower thereon, substantially as specified.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
